Maybe this is not a good example, but I am thinking that something like
OCSP retrieval failing on the client side is not something that would
show up in the webserver logs.
Sure, but doesn't the OCSP site know whether it has set HSTS?
You might be thinking of a different usage of OCSP.

I was thinking about: a browsers gets certificate from TLS. It tries to verify it using OCSP against a third party OCSP server. The OCSP server is down. Now the website the browser is trying to access is effectively down with HSTS enabled.
